Head Detective Juliet Lynn "Jules" O'Hara is a character on the American comedy Psych played by Maggie Lawson. She attended the University of Miami. Fictional biography Juliet O'Hara first appears undercover in the show's second episode, "Spellingg Bee", as a recently transferred junior detective from Miami Beach where she attended the University of Miami, replacing Lucinda Barry as Head Detective Carlton Lassiter's partner after Shawn discovered Carlton and Lucinda were having an affair during the first episode, "Pilot". Born in October 1981, she was raised in a family of brothers and is shown to be close with both her parents and her siblings. Although she is initially frustrated by her coworkers not taking her seriously enough due to her relatively young age, as the series progresses she is given more responsibility, being left in charge in the absence of Lassiter and then Interim Chief Karen Vick. She has grown more assertive with her partner, and actors Maggie Lawson and Timothy Omundson (who plays Lassiter) both suggest that a strange mutual respect has developed between them. Juliet seems to present a gentle counterpoint to Lassiter's gruff, rigid style. She reminds her partner repeatedly to "be sensitive" with the media, the victims, and the witnesses of their cases. Unlike Lassiter, she is friendly with Shawn Spencer and more willing to work with him and Burton Guster. Lawson says that, although Juliet is bemused by Shawn at first, she has slowly gained respect for him and by the second season, Juliet reveals a "very friendly, comfortable relationship". The actress says she thinks that, despite some skepticism, Juliet does believe that Shawn is psychic. By the end of the fifth season, Shawn and Juliet are romantically involved. By the middle of the sixth season, Shawn is ready for marriage. Her older brother Ewan, played by John Cena, is an army soldier whom she had to arrest when he attempted to murder an actual killer to protect the army. Ewan was supposed to go to prison but his high level bosses made him vanish. Juliet claims Ewan was the reason she became a cop, that him joining the military gave her enough confidence to join the police force. Her estranged con artist father Frank O'Hara is played by William Shatner. She seems to be Scots Irish, with her family hailing from Inverness.
